CLOSURE FOR MILK-BOTTLES.

Application filed June 30, 1919.

To all whom it may concern:

Be it known that I, FRANCIS G. LARKIN, a citizen of the United States, residing at Rutherford, in the county of Bergen, State of New Jersey, have invented certain new and useful Improvements in Closures for Milk-Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in milk bottles and particularly to closures therefor.

One object of the present invention is to provide a novel and improved construction of this character wherein the closure plug of the bottle will automatically fall into closure position when the bottle is in an upright position.

Another object is to provide a novel and improved closure for a milk bottle having means for holding the closure against opening movement.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation, partly broken away, of the upper portion of a milk bottle equipped with my improved closure, the closure being in closed position.

Fig. 2 is a vertical sectional view of the upper portion of the bottle showing the stopper in elevated posltion.

Fig. 3 is a horizontal sectional view taken on the line 3-3 ofFig. 2.

Fig. 4; is a top plan View of the bottle, the closure being in closed position.

Referring particularly to the accompanying drawing. 10 represents the neck of the bottle which has the flanged mouth 11 and the internal s ioulder 12 for the reception of the closure plug 13. The inner face of the flan ged mouth is formed with the threads 1s for cooperation with the threads 15, of the closure plug 13, to lock the plug within the said mouth. Projecting from the center of the top face of the plug 13 is a fingerpiece 16 which is adapted to be grasped to rotate the plug when Securing or releasing the same with respect to the threads, and also Specification of Letters Patent.

Patented Jan. 27, 1920.

Serial No. 307,670.

for lifting the plug for the purpose of pouring the contents of the bottle. Extending diametrically across the mouth of the bottle, and on the level of the shoulder 12, is a fiat bar 17 having a central enlarged portion 18 formed with an opening 19. Through this opening is slidably disposed the stem 20 which is carried by the lower face of the plug 13, said stem being formed with an enlarged head 21, on the lower end to prevent the stem being pulled out of the opening.

lVhen the bottle is disposed in an upright position the plug closure 13 will drop into the mouth of the bottle by gravity, but when the contents of the bottle are to be poured, the member 16 is grasped and lifted to raise the plug above the bottle mouth, and the contents emptied. The head 21 insures the retention of the closure in its proper relation to the bottle, whereby it cannot be completely removed or lost. By providing the threaded locking means, the closure can be held in its seated position within the mouth of the bottle, thus protecting the contents from contamination, or loss. The parts may be of course assembled in any manner. In assembling the parts the stem 20 is drawn up through the opening 19 and is then connected to the member 13 in any of the many ways common in the art such as by fusing or by cementing.

What is claimed is:

A bottle and closure therefor including a bottle neck having an internal shoulder forming a seat and internal threads on the mouth of the bottle, a transverse member in the mouth of the bottle in the plane of said shoulder and having a central apertured enlargement, a stem slidable vertically through said aperturel enlargement, a head on the inner end of the stem, and a closure plug on the outer end of the stem formed to fit within the mouth of the bottle and rest on said shoulder, said closure being formed with external threads for cooperative engagement to hold the closure within the mouth of the bottle.

In testimony whereof I afliX my signature, in the presence of two witnesses.
